fix types exposure in build process (#186)

* fix types exposure in build process

- ignore rollup dynamic files
- remove outdated copy script
- fix path of the generated type definition
- remove outdated index.d.ts that contain incoherent duplicated types (probably old type definition)

* move exposed definitions directly at the root of dist instead of dist/src

this fixes typescript error in userland

- restore path of the exposed type definition

* Add types field to package.json

Fixes the types exposure by pointing package.json 'types' field to the generated index.d.ts file. This ensures TypeScript consumers can find the type definitions.

* Extract version to src/version.ts module

Addresses CodeRabbit's concern about rootDir: 'src' constraint.
Instead of importing ../package.json directly from src/FieldArray.ts
(which violates the rootDir boundary), we now:

1. Create src/version.ts that imports package.json and exports version
2. Have FieldArray import from ./version instead

This keeps all TypeScript imports within the src/ directory and
generates cleaner .d.ts files that don't reference ../package.json.
